I would make very wild guess that if all it takes to make it e-ttl compatible, is flashing new firmware, then they have to work in manual mode, since contacts etc. are the same and compatible already and in manual mode all you need is flash trigger.

Of course nothing is better than actual test, so if I was you, I would take my flash to the store and test it to make sure.
